What type of chart is used in agile methodologies to track story points remaining?

The burndown chart is specifically designed to track the amount of work remaining in a sprint or over the course of a project in agile methodologies. It visually represents the work completed versus the work left, typically measured in story points or hours. The chart plots time on the x-axis and remaining work on the y-axis, allowing teams to assess their progress and adjust their efforts accordingly.

The burndown chart offers a straightforward view of the team's velocity and helps to identify trends, such as whether the team is on track to complete the project within the desired timeframe. This is particularly useful for identifying late-stage problems or for making informed decisions regarding future sprints.

In contrast, while the velocity chart does convey information about the amount of work completed over time, it does not specifically focus on the remaining work. Similarly, a Gantt chart is more suited for traditional project management and timelines rather than agile progress tracking, and a Kanban board helps manage flow rather than directly visualize remaining story points. Thus, the burndown chart is the appropriate tool in this context.
